Abstract
The technical problems to be solved in the utility model are a can realize the high -speed dig rig unit head drive arrangement soon who gets rid of soil is provided, the unit head rotational speed can reach 70rpm. Do not adopt state's outward turning to dig the high -speed high -speed soil that gets rid of of native motor realization unit head that gets rid of of two grades rig unit heads or even third gear speed reducer or increase third. The utility model discloses a big moment of torsion variable displacement motor of low -speed and one -level planetary reducer realize the high -speed soil that gets rid of, including the big moment of torsion variable displacement motor assembly of low -speed, one -level planetary reducer assembly and unit head body assembly, the big moment of torsion variable displacement motor assembly of low -speed is connected with one -level planetary reducer assembly through the spline ring flange, and one -level planetary reducer assembly passes through the spline ring flange and links to each other with unit head body assembly, and unit head body assembly is connected with the drilling rod, and the drilling rod is connected with the drilling tool. Low -speed motor drive speed reducer, speed reducer driving power head again are rotatory, on the unit head finally transmits the drilling rod to moment of torsion and rotational speed. The drilling rod transmits moment of torsion to the drilling tool that lies in the drilling rod below again.
Description
Technical field
The utility model belongs to piling machinery technical field, particularly a kind of rotary digging drill power head drive unit.
Background technology
Rotary drilling rig is the principal works machinery of bored pile construction in building foundation engineering, and its advantage is that rotary drilling rig installed power is large, output torque is large, hole quality is good, flexible and convenient operation, efficiency of construction are high, noise is little, environment pollution is little.And coordinate different drilling tools, rotary drilling rig can adapt to the geological conditions of China's most area.During rotary drilling rig work, driving force and the plus-pressure of drilling rod all derive from unit head, and thus rotary digging drill power head is the core component of rotary drilling rig, and the performance of rotary digging drill power head and feature often determine the functional performance of rotary drilling rig.
Rotary digging drill power head domestic at present adopts high speed variable displacement motor assembly and two-stage planetary reducer assembly to drive.Rotating speed due to unit head is limited to the factor of motor, reductor and unit head itself, and when ensureing enough moments of torsion, the maximal rate of unit head is all within 40rpm.
Along with domestic market requires more and more higher to the compliance of the various operating modes of rotary drilling rig, higher requirement is proposed to the range of speeds of rotary digging drill power head, particularly on the small-sized drill of building construction, workshop building etc., require that unit head rotating speed is up to 60rpm, after unit head rotating speed height, to get rid of soil easier for rotary drilling rig drilling tool.In the middle of external prior art, more than 60rpm is realized in order to realize unit head rotating speed, what rotary drilling rig generally adopted is high speed variable displacement motor assembly and two grades even third gear reductor or increase third high speed and get rid of native motor and realize power head height rotating speed and get rid of soil, but such shortcoming is the structure of reductor and controls and power head structure complexity, thus easily breaks down.
Utility model content
The utility model provides a kind of rotary digging drill power head drive unit realizing getting rid of at a high speed soil, it is characterized in that: comprise low-speed big variable displacement motor assembly, primary planet reductor assembly and unit head body assembly, described low-speed big variable displacement motor assembly is connected with primary planet reductor assembly by spline flange; Described primary planet reductor assembly adopts primary planet transmission; Described primary planet reductor assembly is connected with unit head body assembly by spline flange; Described low-speed big variable displacement motor assembly drives primary planet reductor assembly, and described primary planet reductor assembly drives unit head body assembly to rotate; Described unit head body assembly drives drilling rod, and drilling rod is connected with drilling tool.
Preferably, described low-speed big variable displacement motor assembly comprises low-speed big two-stage variable displacement motor or low-speed big stepless variable motor.
Preferably, described low-speed big two-stage variable displacement motor and low-speed big stepless variable motor are hydraulic motor.
Preferably, described unit head body assembly connects one or more groups low-speed big variable displacement motor assembly and primary planet reductor assembly.
The beneficial effects of the utility model are: the combination of low-speed big variable displacement motor assembly and primary planet reductor assembly drives unit head body assembly, compare the structure of high speed variable displacement motor assembly and two-stage planetary reducer assembly, enough moments of torsion can be ensured, primary planet reductor assembly is simpler than two-stage planetary reducer structure simultaneously, not easily breaks down; And low-speed big variable displacement motor assembly and the primary planet reductor assembly of many groups can be used, drive unit head body assembly, thus ensureing on the basis that moment of torsion is enough large, unit head rotating speed is enable to maintain 70rpm, giving full play to the efficiency of rotary drilling rig when getting rid of at a high speed soil, improving rotary drilling rig operating efficiency.
Accompanying drawing explanation
Fig. 1 is rotary digging drill power head drive unit front view, and wherein, 1 is low-speed big variable displacement motor assembly, and 2 is primary planet reductor assemblies, and 3 is unit head body assemblies.
Fig. 2 is the top view of rotary digging drill power head drive unit variable displacement motor.
Detailed description of the invention
The utility model is illustrated below in conjunction with embodiment.As shown in Figure 1, rotary digging drill power head drive unit comprises low-speed big variable displacement motor assembly 1, primary planet reductor assembly 2, unit head body assembly 3, low-speed big variable displacement motor assembly 1 is connected with primary planet reductor assembly 2 by spline flange, primary planet reductor assembly 2 is connected with unit head body assembly 3 by spline flange, unit head body assembly 3 is finally delivered to moment of torsion and rotating speed on drilling rod 4, drilling rod 4 transmits torque on the drilling tool 5 that is connected with drilling rod 4 again, and drilling tool 5 is positioned at the below of drilling rod 4.
Unit head body assembly 3 can be connected with low-speed big variable displacement motor assembly 1 and the primary planet reductor assembly 2 of one group, two groups, three groups or four groups.
When rotary drilling rig works, low-speed big variable displacement motor assembly 1 drives primary planet reductor assembly 2, and primary planet reductor assembly 2 drives unit head body assembly 3 to rotate again.
